best gh1.3 PPro cs5.5 timeline codec (long 90min project multi timelines etc)

Hi all toolman here

just wanted your input on the following situation

what's the best codec to render the mts files to before adding them to a premiere pro 5.5 timeline.

I usually work on quiet large 1 to 1.5 hour projects with 3 camera or so. I find that usually after avoue 1.2 the project is done premiere pro has a wobbler and it takes upwards of 30 seconds for a single frame of video to update in the project window,
then this happens i have to pre render out the time lines at 1/4 resolution just so i can finish the project off.

I'm wondering weather Avid DNxHD or Lagarith codec's might help in the timeline

The avid NDxHD codec renders the mts files to about 77.5 gb of footage per hour in an .mov wrapper and takes about 110min to render on my system (am i right in thinking that the face that its a .mov means that i cannot take advantage of the 64 bit o/s - program

The Lagarith codec renders the 1080p mts files to about 128.4gb of footage per hour in a .avi wrapper and it takes about 98min to render

adding both to a 1080p timeline i discovered that that during playback of the avid DNxHD file my cpu usage on all 4 cores was about 85 to 90% - playback of the Lagarith formated file my cpu usage (4 cores) was around 55%


I usually work as follows

I place all the footage from the 3 separate cameras onto 3 separate time lines and sync them. Then onto these video files on the time lines I color grade as needed (THEN I TURN OFF THE COLOR GRADING EFFECTS ON ALL THE FILES ON THESE 3 TIMELINES)

I then add these 3 timelines to a master time line as 3 separate sequences and proceed to edit / chop out what i need.

thanks in advance for any help / thoughts on this - particularly interested in people whe edit long timelines similar to mine as to what codec they render to first.

Transcoding to Cineform works great (but not free).

Depending on how much computer memory you have - that might be worth upgrading also?

Edit: just saw you have 8gb, so yeah more would likely help with avoiding the slowdown.
 
Thanks for reply ATM I cant get 16gb for my mother board

-re the cineform transcoding is it a codec that can be installed into premie pro or is it a stand alone programme that is use to first transcode the mts files to cineform - which then can be imported and edited in premiere pro.

Thanks for quick reply

any one have info / thoughts on the cineform codec / program i.e. is it a downloadable codec for premiere pro or is it a stand alone video editing program etc.

thanks in advance

I like DNxHD and have been using it for some time now. Did you realize there are different quality settings? Some are less compressed than others which will give bigger files, but use less cpu to playback/scrub.

This might be a silly question, but have you turned CUDA on in Premiere?
